Well, if I use '%{' in the string and escape the % with a \, I get 'rad_expand_xlat: Invalid variable expansion passed as argument' as error message, but the output is nothing, which of course means nothing gets set.

So I guess it's only if the } gets involved that things go badly wrong (i.e. that the resulting attribute contains a }, part of the salt, and part of the host/realm/COI name).

I'll submit a PR for the updates.
